Cutting & welding
Cleaner, greener welding
Cold pressure welding has
many benefits. Compared
with electrical welding, the
process is quick, clean, ‘green’
and cost effective and creates
a reliable, permanent weld
stronger than the parent
material without sacrificing
electrical integrity.
British company PWM,
which has been at the
forefront of cold pressure
welding technology for over
30 years, has developed a
comprehensive range of
robust, reliable machines and
dies suitable for a variety of
applications.
PWM dies, which can be
standard or custom made
to suit round or profile
wire and rod, are precision
engineered in the company’s
own workshops, ensuring
total quality control and
accountability.
PWM’s most recent intro-
duction is an upgraded
version of its powerful
electro-hydraulic P1500 rod
welder, launched at wire
2010.
The new P1500 has an improved hydraulic operating system that provides a quieter, smoother weld operation. The machine also
incor- porates a new user-friendly operator keypad. Power consumption is limited to the hydraulic pump motor, making the
P1500 very energy efficient and economical to operate.
The P1500 weld cycle takes only minutes and the machine has a capacity of 15mm to 25mm diameter copper and 15mm to
30mm aluminium.
The PWM range includes two smaller rod welders, the P1000 (6mm to 20mm) and the EP500 (5mm to 15mm) as well as manual
hand-held and bench-mounted machines, and trolley-mounted machines (manual and powered) for wire sizes from 0.1mm up to
6.5mm. Cold welding can be used to bond
most non-ferrous metals, as well as various
alloys. The process can also be used to join
dissimilar materials, for example, aluminium
to copper, and materials of different sizes.
PWM’s UK-based specialist team is always
happy to provide advice and support
on cold welding techniques and appli-
cations and the company’s worldwide
network of experienced agents offers
international wire and cable manufacturers a
fast and efficient service.
